Abstract

Due to the capture process, video signals are generally
contaminated by noise. Furthermore, overall video quality can be
improved by reducing sharpness in fast moving areas, except in
cases where the eye is able to track the motion. In this paper we
propose a relatively simple pre-processing method that is able to
address both these situations. The proposed pre-processing
algorithm is based on selectively removing high frequencies that
are not well predicted by the motion compensation. While the
decision is made based on temporal tracking, the filtering is done
exclusively in the spatial domain, thus avoiding the artifacts
produced by other pre-processing methods.
